PIPE-WRENCH.

SPECIFICATION forming part of Letters Patent No. 626,037, dated May 30,1899. 2

Application filed November 30,1898. Serial No. 697,857. (No model.) I

To all whom it may concern:

Beit known that 1, JAMES J.RH1NELAN1)ER, a citizen of the United Statesof America, residing at Harmony, in the county of Butler and State ofPennsylvania, have invented certain new and useful Improvements in Pipe-Wrenches, of which the following is a specification, reference being hadtherein to the accompanying drawings.

Myinvent-ion relates to certain new and useful improvements inpipe-wrenches.

The particular object of my invention is to produce a pipe-wrenchwhichcan be used with pipes of different diameters, which will be simple inconstruction, and which will be durable in use.

Fora better comprehension of myinvention attention is attracted to theaccompanying drawings, forming a part of thisspecification, in whichFigure 1 is a perspective view of a form of my improved wrench, showingthe pipe attached therein in-dotted lines. Fig. 2 is a perspective viewof a rigid jaw formed on the upper end of the handle of the wrench. Fig.3 is a perspective view of my preferred form of wrench,having thesliding supporgto which the clamping-jaws are pivotally secured. Fig. 4is a vertical sectional view thereof. Fig. 5 is a vertical sectionalview of the sliding support for the clamping-jaws. Fig. 6 is a verticalsectional view of the adjusting-collar. Fig. 7is a top plan view of theadj usting-collar shown in Fig. 3.

Referring to the drawings, 1 indicates the handle of the wrench, whichmay be of any desirable length, having formed on two opposite sidesthereof the threads 2, upon which the adjusting-collar 3 operates.Formed integral with the upper end of the handle 1 is the rigid jaw 4,the-edge thereof being somewhat concaved and formed with'a series ofgripping-teeth 5, as shown. The rigid jaw is formed with an aperture 6to receive the pin 7 for pivotally securing thereto the clamping orgripping jaws 8 and 9. The clamping or gripping jaws 8 and 9 are cutaway on a portion of their .inner face, as at 10, to'allow of theiroperating over the edges of the rigid jaw, as shown. The jaws 8 and 9are formed as shownthat is, bent outwardly at an incline, as at 11, theninwardly at an incline, as

at 12, then downwardly on an incline, as at 13, the portion 13 being atthe outer end of the jaws, forminga hook, and provided on its inner facewith a series of gripping-teeth 14.

In the preferred form (shown in Fig. 3) I provide an elongated slot 18in the rigid jaw, in which the pivotal pin 19 operates. Pivotallymounted upon the pin 19 are the clamping or gripping jaws, which are ofthe same construction as that shown in Fig. 1, and rigidly mounied onthe pin 19, as shown, is the adjustable support 20. port 20 is providedat its lower end on the inner face with a collar 21, which is adapted tosupport the adjusting-collar 22, as shown. The side of the adjustablesupport converges inwardly, as at 2-3, to allow the adjusting-collar tocarry the ad just-able support in the outward direction owing to theelongated slot, and thereby spread the clamping or gripping jaws. Theupper end of the adjusting-collar 22 is. formed with an extending flange24 to prevent the same from becoming disconnected from the adjustablesupport.

It is thought that the operation of my improved wrench, as well as itsmany advan what I claim as new, and desire to secure by Letters Patent,is

1. In a pipe-Wren ch, a handle having a rigid jaw formed integral withits one end, said,

handle being also provided with a series of threads, an adjusting-collar operating on said threads and a pair of clamping orgripping jaws pivotally secured to said rigid jaw, substantially asdescribed.

The adjustable sup 2. In a pipe-wrench a handle having a portion of itsupper'end formed with a series of upper portion thereof formed with aseries of threads, an adj usting-collar adapted to operate on saidthreads, a rigid jaw formed integral with the upper portion of saidhandle, said handle having an elongated slot formed therein, a pivot-pinadapted to operate in said slot, apair of clamping or grippingjawsadapted to be pivotally secured to said pin, and a support secured tosaid pin adapted to support at its lower end the said adjListing-collar, substantially as shown and described.

4:. In a pipe-wrench, a handle, a series of threads formed on the upperportion thereof, an adjusting-nut adapted to operate on said threads, arigid jaw formed integral with the upper end of said handle the edgethereof being somewhat concaved and formed with a series ofgripping-teeth, a series of grippingjaws pivotally secured to said rigidjaw which are bent outwardly at an incline, then upwardly at an inclinethen downwardly at an incline having a series of gripping teeth formedon the inner face of the downwardlyinclined portion, substantially asshown and described.

In testimony whereof I affix my signature in the presence of twowitnesses.

JAMES J. RHINELANDER.
